The chief infectious disease specialist of the United States, Anthony Fauci, said that the mu-strain of the coronavirus causes concern among specialists.
“He has some mutations, which indicates the ability to evade the protection of certain antibodies,” the expert explained to CBS.
Nevertheless, as Fauci noted, now the “mu” strain does not pose a serious threat since another variation of the virus, “delta,” still dominates in the United States.
He added that specialists closely monitor the coronavirus mutations, and the mu strain, in particular, is taken very seriously.
A variant of the coronavirus B. 1.621, known as the “mu” strain, was detected in January 2021 in Colombia. It is distributed in 40 countries, including Peru, Chile, the USA, and others. At the end of August, the World Health Organization called it a “variant of interest” because of the mutational insertion of 146 N and several amino acid substitutions in the spike protein.
